1. How many milliliters are in 2 liters?

• A. 2000 mL
• B. 20,000 mL
• C. 200 mL
• D. 2 mL

Correct answer: A

Rationale: There are 1000 milliliters in 1 liter, so 2 liters equal 2000 milliliters. The conversion is based on the fact that the prefix 'milli-' means one-thousandth. Therefore, the correct answer is 2000 mL. Choice B, 20,000 mL, is incorrect as it multiplies 2 liters by 10. Choice C, 200 mL, is incorrect as it divides 2 liters by 10. Choice D, 2 mL, is incorrect as it incorrectly assumes that 2 liters is equal to 2 milliliters.

2. Is 0.25 mg equal to 250 mcg?

• A. TRUE
• B. FALSE
• C. Sometimes
• D. None of the above

Correct answer: A

Rationale: The correct answer is A: TRUE. 0.25 mg is indeed equal to 250 mcg. This conversion is obtained by multiplying 0.25 mg by 1000 to convert it to micrograms. In pharmaceuticals, it is crucial to understand and convert between different dosage units accurately. Choice B is incorrect as the two quantities are equivalent. Choice C, 'Sometimes,' is misleading as the conversion from milligrams to micrograms follows a consistent ratio. Choice D, 'None of the above,' is incorrect as there is a definitive equivalence between the provided quantities.

3. What is 0.875 as a fraction?

• A. 7/8
• B. 9/10
• C. 5/6
• D. 3/4

Correct answer: A

Rationale: To convert 0.875 to a fraction, you can write it as 875/1000. Simplifying this fraction by dividing the numerator and denominator by their greatest common divisor, which is 125, gives you 7/8. Therefore, the correct answer is 7/8. Choice B (9/10), Choice C (5/6), and Choice D (3/4) are incorrect as they do not represent the fraction equivalent of 0.875.

4. How many millimeters (mm) are in 3.45 meters?

• A. 345 mm
• B. 3,450 mm
• C. 345,000 mm
• D. 3.45 mm

Correct answer: B

Rationale: To convert meters to millimeters, you need to multiply by 1,000 because there are 1,000 millimeters in a meter. Therefore, 3.45 meters × 1,000 = 3,450 millimeters. Choices A, C, and D are incorrect because they do not reflect the correct conversion factor from meters to millimeters.

5. What is 0.16 as a fraction?

• A. 16\100
• B. 16\1000
• C. 4\25
• D. 4\50

Correct answer: C

Rationale: To convert 0.16 into a fraction, you write it as 16\100, which simplifies to 4\25. This fraction is in its simplest form and accurately represents the original decimal value without further reduction. Choice A (16\1000) is incorrect because the fraction is not simplified, and Choice D (4\50) is incorrect as it simplifies to 2\25, not representing the original decimal value. Therefore, Choice C is the correct answer.
